Data Sheet
Cisco Long-Reach Ethernet
Solution
The Cisco Long-Reach Ethernet (LRE)
networking solution delivers cost-effective,
high-performance broadband access to
multiunit (MxU) buildings (hotels, residential
multidwelling units [MDUs], and multitenant
unit [MTU] office buildings) and enterprise
campus environments such as manufacturing,
educational campuses, and medical facilities.
Cisco LRE technology dramatically extends
EthernetoverexistingCategory1/2/3wiringat
speeds from 5 to 15 Mbps (full duplex) and
distances up to 5,000 feet. (Actual achievable
data rates depend on cable quality, noise and
cross talk environment.) The Cisco LRE
technology delivers broadband service on the
same lines as Plain Old Telephone Service
(POTS), digital telephone, and ISDN traffic.
In addition, Cisco LRE supports modes
compatible with asymmetric digital subscriber
line (ADSL), allowing service providers to
provision LRE to buildings where broadband
services already exist.

Catalyst 2900 LRE XL Desktop Switches
Cisco Catalyst 2900 LRE XL switches are based on the
Ciscomarket-leadingCatalyst2900SeriesXL3.2-Gbps
switch architecture, and include all Enterprise- class
features (all ports) available in Catalyst 2900 XL
switches. Now, service providers can use the
industry-leading Catalyst switch platform to address a
broad range of wiring environmentsbeyond Category5
cabling.This givesusers a low-cost,end-to-endsolution
and eliminates the need to train installation teams on
multiple systems.
The Catalyst 2924 LRE XL has 24 Long-Reach
Ethernet ports and four 10/100 Ethernet ports; the
Catalyst 2912 LRE XL has 12 LRE ports and four 10/
100 Ethernet ports. Both switches are one rack-unit
(1RU) high, 13-inches deep, and can be either mounted
on a wall or placed on a rack. In addition, Cisco LRE
switches feature integrated LRE technology, which
meansthattheydonot require anexternalmodempool.
The result is a compact, cost-effective form factor that
allows service providers and building owners to build
high densities with a minimum footprint.
Catalyst 2900 LRE XL switches deliver dedicated
bandwidth per port at rates up to 15 Mbps. LRE
transmissions coexist with POTSand ISDN, and can be
compatible with ADSL trafficin the same building. The
switches can be configured on a per-switch basis to
support the following modes:
5 Mbps symmetrical rate (up to 5,000-feet distance)
10 Mbps symmetrical rate (up to 4,000 feet)
15 Mbps symmetrical rate (up to 3,500 feet)
The Catalyst 2924 LRE XL and2912 LRE XLswitches
provide fast and easy connectivity into building patch
panels with one RJ-21 telco connector. The 10/100
Ethernet ports can be used to connect servers,
daisy-chain multiple LREswitches, oruplink to a Cisco
Catalyst 3500 XL, 2900 XL, or 2948G-L3 10/100
Ethernet switch. These connectivity options provide
multiple price/performance options to meet building
and budget requirements.
The Cisco LRE switches provide the important features
necessary for robust networks:
Quality of Service: 802.1p QoS support. Provides
high- and low-priority queuing on a per-port basis.
Layer 3 QoS support—including DiffServe and
application-based queuing—when Catalyst
2924 LRE XL and 2912 LRE XL switches are
aggregated by a Layer 3 switch.
Scalability: Up to 15-Mbps symmetric performance
over single-pair wiring. Fast EtherChannel
®
port
aggregation.
Security: 802.1Q port-based virtual local-area
network (VLAN) support. Cisco private VLAN
access, assuring port security without requiring a
VLAN per port. Access control list (ACL) security
when a LRE switch is aggregated by a Cisco Layer 3
10/100 Ethernet switch.
Network Management: Cisco Switch Clustering
technology and the advanced, Web-based Cisco
Cluster Management Suite (CMS) software deliver
easy-to-use configuration and ongoing monitoring
and management of up to 16 switches in multiple
building sites from the point-of-presence (POP).
This software is embedded in the Catalyst
2924 LRE XL and 2912 LRE XL switches and
delivers remote, intuitive management of clustered
switches and connected Cisco 575 LRE and 585
LRE CPE devices through a single IP address. Cisco
Catalyst LRE switches also feature Cisco IOS
®
software and command-line interface (CLI),

Cisco LRE switches are easy-to-configure and deploy,
and offer a compelling option in terms of cost,
performance, scalability and services compared to
traditional ATM-based xDSL solutions and other
hybrid DSL technologies, such as Home Phoneline
Networking Alliance (HPNA).
Cisco 575 LRE CPE Device
Each LRE portis terminatedin theroom withthe Cisco
575 LRE Customer Premise Equipment (CPE) device.
This compact device bridges LRE and Ethernet, and
provides oneRJ-45 Ethernetconnection andtwo RJ-11
connectors—one for the wall and one for a telephone.
The Cisco 575 LRE CPE device can be mounted on or
under a desk, or on a wall. It ships with a mount
lock-in mechanism and clip-on Ethernet cable guard to
discourage theft, as wellas an Ethernet cord.The Cisco
575 LRE CPE device supports POTS traffic—including
ISDN or digital phones—that coexists over the same
LRE line by splitting LRE and POTS traffic at the CPE
device. A POTS Splitter is required for connectivity to
the PBX and LRE switch stack.

Cisco 585 LRE CPE Device
The CISCO585-LRE is a four-port CPE device for the
LRE solution. The Cisco 585 CPE and the current 575
CPE are fully interoperablewith the 2924-LRE-XL and
2912-LRE-XL switches. The Cisco 585 CPE shares the
same basic form factor as the current 575 CPE and has
four Fast Ethernet ports allowing customers to connect
multipledevicessimultaneously.TheCisco585CPEalso
has two RJ-11 connectors: one for ananalog phoneand
one for the LRE link (same as the 575 LRE). A section
of the top of the Cisco 585 CPE is indented to allow
customers to place customized labels, and themounting
templates on both the Cisco 585 CPE and 575 CPE are
identical allowing customers to easily replace existing
575 CPEs mounted under desks with Cisco 585 CPEs.
The Cisco 585 is targeted towards customers who
intend to deliver converged voice, video, and data
services to several devices such as computers, set-top
boxes, IP phones, wireless access points, and so on.
In order to support converged service such as
video-on-demand, the Cisco 585 CPE supports
802.1p QoS with two priority queues allowing voice
and video traffic to be prioritized over normal data
traffic. The speed of the four Fast Ethernet ports is set
to auto-negotiate, and the duplex is fixed at half.
Cisco LRE 48 POTS Splitter
The Cisco LRE 48 POTS Splitter is a high-density,
low-cost device that is ideal for building deployments
where the PBX system is on-site and POTS traffic must
coexist over the same copperwiring as LRE traffic. The
Cisco LRE 48 POTS Splitter enables the coexistence of
LRE and POTS on the same telephone line. Unlike
“splitterless” building broadband network solutions,
the Cisco LRE 48 POTS Splitter ships as a separate,
compact form factor to ensure that POTS service is
separate, and never compromised by LRE switch
reconfigurations or downtime.
The Cisco LRE 48 POTS Splitter supports 48 ports
in a 1RU form factor. Each splitter has six RJ-21
connectors—two each for connectivity to the patch
panel, the LRE switch(es), and the on-site PBX system.

Long-Reach Ethernet Technology
Long-Reach Ethernet provides an extensionto theIEEE
802.3-compliant Ethernet standard network. LRE
extends Ethernet over single-pair wiring at distances of
up to 5,000 feet. Cisco LRE technology combines
simple and standards-based LAN connectivity and
extensionoverexistingtelephonewiring,whileboasting
several competitive advantages. The Cisco LRE
technology provides a point-to-point link that can
deliver half- or full-duplex Ethernetat upto a15-Mbps
data rate. Cisco LRE technology supports transmission
of POTS, PBX, or ISDN signaling simultaneously with
data over the standard telephone-grade wire
infrastructure, and can be provisioned in the same wire
bundle as ADSL.

The technology employs Quadrature Amplitude
Modulation(QAM).QAMmodulationusesbothsignal
amplitude and phase to define each symbol. LRE uses
the most sophisticated QAM technology with various
QAM modulations (QAM-256, QAM-128, QAM-64,
QAM-32,QAM-16,QAM-8,andQAM-4).Thesystem
administrator may choose profiles that use different
modulations and frequency plans according to the line
specification and rate definition. LRE is designed
to support multiQAM in order to achieve performance
as close to the physical limit as possible, while
maintaining low cost and low power.
Cisco LRE facilitates the transport of symmetrical,
bi-directional data overunshielded, coppertwisted-pair
telephone wires originally intended for the frequency
band between 300 Hz and 3.4 KHz. The system
employs Frequency Division Duplexing (FDD) to
separate the downstream channel, the upstream
channel, and POTS, ISDN, or PBX signaling services in
the frequency domain. Thisenables service providers to
overlay LREon existing POTS, ISDN, orPBX signaling
services without disruption.Both LREand POTS/ISDN/
PBX services may be transmitted over the same line
without interfering with each other.
